# Contact TB-500 MD: Editorial Corrections and Source Queries | TB-500

> Contact TB-500 MD with corrections, source queries, or citation questions about the TB-500 research dossier. An editorial project — not a clinic, not a vendor, and not a route to obtain any compound.

For editorial corrections, citation questions, and source queries about the TB-500 dossier.

## Reach the editors

This is the contact page for TB-500 MD, an independent editorial digest of the research on the thymosin beta-4 fragment. Use the form to send a correction, ask about a citation, or flag a source you think we have read wrong. We read every message about the accuracy of the record.

A few things this channel is not. It is not a clinical service: we cannot answer questions about personal health, suitability, dosing, or administration, and we do not provide medical advice. It is not a storefront or a supply route: we do not sell, source, or broker TB-500 or any other compound, and we cannot point you to anyone who does. Messages asking where to obtain the substance will not receive a sourcing reply.

## What we respond to

We prioritize messages that improve the dossier: a citation that does not resolve, a study we should add, a place where our species labeling or our full-length-versus-fragment flag could be clearer, or a regulatory fact that has changed and is confirmable from an authoritative source. If you are writing about the FDA 503A status, a link to the primary FDA page helps us verify and update quickly.

The contact form collects only what we need to reply. We do not use it to offer products, and submitting it does not create any clinical relationship. For the regulatory picture, see [TB-500 legal status and 503A access](/legal-status); for the evidence, see the research and references pages.
